„Whether at home, in a business, or at a public authority, protecting valuables and sensitive items requires the right security solution. A safe, technically called a security container or secure cabinet, is at the heart of physical protection. Its sturdy construction is important, but the quality of the lock and professional installation are even more critical.“
EN 1143-1 and EN 1300: Key Standards for Safes and Locks
European standards play a crucial role in ensuring security. EN 1143-1 defines the requirements for security containers, while EN 1300 sets the standards for high-security locks. These standards are internationally recognized benchmarks that make resistance to burglary measurable. A clear understanding of how each safe grade corresponds to the requirements of EN1143-1 makes it easier to select a safe that provides the appropriate level of protection.
Certification by independent bodies such as VdS Schadenverhütung GmbH or the ECB·S of the European Security Systems Association (ESSA) is essential. Compliance with these standards is often a prerequisite for insurance coverage. However, the final insurance level must always be agreed upon with the respective provider.
Classification and Resistance
Safes and strongroom doors are classified under the European standard EN 1143-1 into different resistance grades:
- Grade I to VI: Security containers
- Grade VII to XIII: Strongrooms or vaults
Grade I represents the lowest level of resistance, while Grade XIII represents the highest. This classification is based on comprehensive break-in tests conducted by independent certification bodies as part of the certification process. These resistance levels directly define the safe grade used by manufacturers and insurers.
The type of lock required depends on the resistance grade of the safe or door. Higher grades require more sophisticated locking systems. High-security locks are certified in Europe according to EN 1300 and classified as A, B, C, or D. In German-speaking countries, VdS classifications 1, 2, 3, and 4 are also commonly used.
In addition to the standards mentioned, high-security locks can now also be certified for network operation, with VdS 3841 and EN 17646 defining the most up-to-date requirements for digital security. Depending on the security grade of the safe, one lock—or, if necessary, multiple locks—must meet a specified minimum lock class, such as VdS 2 (B), 3 (C), or 4 (D).
